The spongy and soft bone marrow may be located in the centre of your larger bones. More than 200 billion new red blood cells, white blood cells, and platelets are produced every day. However, it fails miserably in those with bone marrow illness, which includes various forms of cancer. For many people, a bone marrow transplant is their only hope for survival and a chance at a cure.

Important Information Regarding Bone Marrow Transplants

In the case of a bone marrow transplant, healthy tissue is substituted for sick bone marrow. Typically, this healthy tissue consists of blood stem cells. Hence, bone marrow transplants are often referred to as stem cell transplants. Allogeneic transplantation (ALLO transplant) is the process through which a patient receives blood stem cells from a donor's bone marrow. Both peripheral blood and umbilical cord blood can be used as sources for the donor stem cells.

The catch is, however, that there is a catch. Human leukocyte antigen (HLA) typing is used to locate a compatible donor for an ALLO transplant. HLAs, which are unique proteins found on the surface of white blood cells and other cells, are the focus of this specialised blood test. Graft-versus-host disease, a potential complication of transplantation, is less likely to occur with HLA-matched bone marrow (GVHD). What we call graft-versus-host disease (GVHD) occurs when the recipient's immune system mistakes the transplanted tissue for a threat.

Fewer than one-third of transplant patients are able to locate a close relative who is an HLA-match. Bone marrow from donors who share a patient's HLA type is only needed for the remaining 30% of cases. As of 2016, this equates to over 14,000 persons in the United States, ranging in age from infants to seniors, who are in need of an unrelated donor.

The procedure for donating bone marrow

A PBSC collection will most likely be performed on you if you consent to donate bone marrow. What happens is this:

  • A white blood cell growth hormone called granulocyte colony-stimulating factor (G-CSF) will be injected into you once a day, for five days prior to the donation.
  • On day 5, you'll have a needle inserted into each arm by a medical professional. Blood is drawn with only one needle, and then the machine does the rest, cycling the blood and collecting the stem cells. The second needle is used to reinject the blood into the body. The whole thing takes around 3 hours and may be done again on another contribution day if necessary. Headaches, bone pain, and discomfort from the needles themselves are all possible negative outcomes.

Donors are sometimes requested to have bone marrow harvested, a surgical procedure in which the donor's hip bone is opened and the bone marrow is removed. Normal activities can be resumed within a week for most donors after they have undergone the procedure and returned home the same day. Nausea, headache, and exhaustion are common adverse reactions, and they are typically caused by the anaesthetic. Pain or bruising in the lower back is also prevalent.
